CAR-DOOR LOCK.

Application filed December 9, 1814;.

To all whom it may concern:

Be it known that l, Josnrrr VANYO, a subject of the King of Hungary, residing at Warren, in the county of Marshall and State of Minnesota, have invented certain new and useful Improvements in Car-Door Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to car door locks and has for its object to provide a lock of such class, in a manner as hereinafter set forth, which is comparatively simple in its construction and arrangement, strong, durable, efficient in its use, conveniently operated and inexpensive.

A further object of the invention is to provide a car door lock, with means in a manner as hereinafter set forth, to provide a series of locking members simultaneously engaging with the bolt of a lock to prevent the shifting of the bolt until the retaining members have been moved out of engagement therewith.

1Vith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :Figure 1 is a front elevation of a car door lock in accordance with this invention showing the adaptation thereof in connection with a door. Fig. 2 is an end view. Fig. 3 is a rear elevation with a portion of the casing removed and certain of the elements illustrated in dotted lines. Fig. 1 is a cross sectional view. Fig. 5 is a sectional plan.

Referring to the drawings in detail 1 denotes the car body and 2 the car door and to the latter is secured a lock casing 3 and to the former a plate 1, provided with means to constitute a keeper 5 for a shifting lock bolt 6. The latter is of greater length than the keeper 5, and is formed with a longitudinal slot 7, through which extends a pin 8 carried by the keeper 5, to limit the shifting movement of the bolt 6 in either direction. One

end of the bolt'6 is provided with a series of notches 9 and the other end is formed with a grip or handle 10.

The reference character 11 denotes a support, which is recessed as at 12 for the reception of a portion of a plate -1 and said support is interposed between the car body 1 and the plate a and associated with the keeper 5, in fact the support 11 provides the inner wall of the keeper 5 against which slides the bolt 6. Hold fast devices 13 are employed for securing the plate l, and said support 11 to the car body 1.

'l'he lock casing 3 comprises a body portion 11 formed with a longitudinal groove 15 for the reception of a notched end of a bolt 6, as illustrated in Fig. 3, and said body portion 11 is furthermore provided with spaced transverse pockets 16, which open into the groove 15. Recesses 17 are formed in the body portion 11 and which open into the pocket 16. The pockets 16 are intersected by a longitudinal channel 18.

Arranged within each of the pockets 16 is a tumbler 19, formed with an opening 20 intermediate its ends and one side wall of said opening is curved as at 21, and the other side Wall curved as at 22. The curvature of said walls being such that the walls will extend toward each other. One end of the tumbler 19 is beveled as at 23, and the other end formed with a pin 2 1 which extends into the recess 17, and surrounding the pin 24 and interposed between one end of the pocket 16 and that end of the tumbler 19 from which the pin 24. extends is a coil spring 25, the function of which is to normally maintain the member 17 projected from one end of its pocket 16.

The openings 20 of the tumblers 19, when these latter are mounted in the pockets 16, are arranged in alinement, and extending through said alining openings 20 is a key shank 26 and which is provided with a series of bits 27, adapted to engage the side walls of the members 19 for shifting these latter. One end of the key shank 26 is journaled as at 28 to the body portion 1 1 and said key shank 26 has a handle 29 formed with a right-angular disposed lug 30, thelatter having an opening 31, for the passage of a staple 32, to receive a seal. The shank 26 projects from one side of the lock casing 3 and the handle 29 is arranged forward with respect to the plate l. The

handle 29 is of greater diameter than the shank :26.

The lock casing further includes a plate 33 which is secured to the body portion 14 by bolts 34 and said plate 33 maintains the tumbler 19 and key shank 26 in position.

When the bolt 6 is forced into the groove 15, the springs 24 will cause the tumblers 19 to engage in the notches 9. To release the tumblers 19 the key shank is turned in one direction, so that the bits 27 will ride againsi the curved walls 22, under such conditions moving the tumblers 19 fro-1n the notches 9 and the bolt 6 can then be withdrawn, releasing the door.

What I claim is v 1. A car door lock comprising a lock casing,.a plate having a keeper, a bolt carried by said keeper and extending therethrough and having one end formed with notches, spring controlled locking members arranged within said casing and adapted to engage in the notched end of said bolt to release movement of the latter, a shifting element for said members, said element extending through said members and provided with means engaging therewith for moving them from engagement with said bolt when said element is shifted in one direction.

2. A car door lock comprising a lock casing, a plate having a keeper, a bolt carried by said keeper and extending therethrough and having one end formed with notches, spring controlled locking members arranged within said casing and adapted to engage in the notched end of said bolt to release movement of the latter, ashifting element for said members, said element extending through said members and provided with mean engaging therewith for moving them from engagement with said bolt when said element is shifted in one direction, and

means for limiting the shifting movement of said bolt.

3. A car door lock comprising a lock casing, a plate having a keeper, a bolt carried by said keeper and extending therethrough and having one end formed with notches, spring controlled locking members arranged within said casing and adapted to engage in the notched end of said bolt to release movement of the latter, a shifting element for said members, said element extending through said members and provided with means engaging therewith for moving them from engagement with said bolt when said element is shifted in one direction, and means for limiting the shifting movement of said bolt, and means to prevent movement of said element when said members are in engagement with the bolt.

4:. A car door lock comprising a lock casing, a plate having a keeper, a bolt carried bysaid keeper and extending therethrough and having one end formed with notches, spring controlled locking members arranged within said casing and adapted to engage in the notched end of said bolt to release movement of the latter, a shifting element for said members, said element extending through said members and provided with means engaging therewith for moving them from engagement with said bolt when said element is shifted in one direction, and means to prevent movement of said element when said members are in. engagement with the bolt.

In testimony whereof I aflix my signature in the presence of two witnesses.
